October is still a good time to repot many evergreens, such as olives, pyracantha and buxus. Chinese elms can be repotted almost any time of the year, so now is also a good time for working on them.

The other main activity most suitable during spring is pruning and styling, as many trees will be growing vigorously. Trimming and training of new growth is one of the most important activities for the bonsai artist, keeping in mind what future development you want to see in your tree.
